Abstract
A mobile device and a method for managing the power consumption of the mobile device use geomagnetic sensors to determine if an external object is present. If an external object is approaching the mobile device, a near field communication unit is powered on and may communicate with the external object. Additional sensors may determine if the external object may be capable of NFC. Other components of the device may be powered on or off according to the presence of the external device.
